How we approach it

Land clearing to final grade

Earthwork carries the largest single-line risk on most projects, because a volume error compounds through haul, disposal and import.

Cut and fill volumes are calculated with swell and shrinkage by material type. Haul is its own line against a stated disposal distance. If the geotech suggests unsuitable material, it goes on the exclusions list rather than quietly into a unit rate.

What we look for specifically

Swell and shrink ignored, haul distance assumed, unsuitable material absorbed into the excavation rate, and dewatering missed on high-water-table sites.

Typical scope coverage

Civil & Sitework

  • Clearing and grubbing by acreage and density
  • Topsoil strip, stockpile and respread volumes
  • Cut and fill with swell and shrink by material
  • Haul, import and disposal as separate lines
  • Trenching, bedding, backfill and compaction
  • Storm, sanitary and water runs with structures
  • Subgrade prep, base course and aggregate
  • Asphalt tonnage, flatwork and curb LF
Trades in this sector

The packages civil & sitework bids usually turn on.

Each one has its own page covering how that trade is measured, the units it is measured in, and the errors we look for.

Division 31

Earthwork & excavation

Cut and fill volumes with swell and shrink by material type, haul priced separately against a stated disposal distance.

Division 32

Sitework & paving

Asphalt by tonnage, flatwork by area, base course by depth, with curbing, striping, fencing and landscaping counted individually.

Division 33

Site utilities

Storm, sanitary, water and dry utilities measured by diameter and material, with structures counted and trench work priced separately.

Division 03

Concrete

Footings, slabs, walls, grade beams, reinforcement and formwork, measured by system and location rather than as one running volume.

Civil & Sitework questions

What contractors ask us first.

It is flagged from the geotech report as either a quantified line or a written exclusion. It is never silently absorbed into an excavation rate, because that turns a known risk into a hidden one.

Yes, as its own line against a stated disposal distance. Keeping it separate means the assumption most likely to change can be repriced without touching the excavation quantities.

Yes, and they are a large part of the sitework work we do. Single-trade earthwork packages are often the fastest way to start.
